  • Patent number: 4357879
    Abstract: A bolsterless bogie for rail vehicles has at least one link which is directly connected to the bogie frame and the rail vehicle center pivot by means of wear-free rubber joints and connecting pins. Rubber buffers limit the transverse motion between center pivot and bogie frame; vertical forces are transmitted by air-spring bellows arranged in the vehicle center plane between the underframe and the bogie side sill, and stops effective in the travel direction are provided between center pivot and bogie frame.

  • Patent number: 4353293
    Abstract: An espresso machine has a coffee brewing chamber, a water reservoir and a water heater. Two electrical pumps are provided, one capable of supplying a smaller quantity of water from the reservoir via the heater to the brewing chamber so as to make a regular-strength coffee beverage, and the other capable of supplying a considerably larger quantity of water from the reservoir via the heater to the brewing chamber, so as to make a weaker-strength coffee beverage from an identical quantity of coffee. A selector at the outside of the machine allows a user to select which one of the pumps he wishes to energize.

  • Patent number: 4352683
    Abstract: An apparatus for venting and deaerating a liquid circuit, such as the coolant circuit of an internal combustion engine, has a surge tank with an air-side port and a liquid-side port. Installed in the air-side port is a tube, through one end of which liquid to be deaerated is admitted at a certain velocity. The tube has a longitudinally extending lateral slot through which the admitted liquid is discharged; opposite the slot is located a baffle onto which the discharged liquid impinges over a large surface area. This causes even small air bubbles to be liberated from the liquid so as to remain in the air-side part, whereas the deaerated liquid runs off the baffle and into the liquid-side part of the surge tank.

  • Patent number: 4346651
    Abstract: A toaster has a casing, two or more walls of which define between themselves an upright food-receiving space, and a base defining with the lower edges of these walls a clearance open to the food-receiving space. A separate food carrier is insertable into the clearance so that food-holding portions of the carrier project from the clearance into the space. Heating elements toast or warm the food in the space. Guides are provided to facilitate insertion and withdrawal of the carrier from the clearance.

  • Patent number: 4337122
    Abstract: A new and useful coke oven door which is simple in construction but provides complete sealing efficiency. A pair of supporting holes are formed on each of upper and lower portions of the side plates of the door body, and through the supporting holes a locking bar extends which has on the center portion an arm for rotating and on both ends rollers eccentrically located with respect thereto. By rotating the locking bar with the arm, the door can be moved slightly backward or forward when removing or installating lest the knife edge should scratch the door sealing frame.

  • Patent number: 4318345
    Abstract: A vestibule connection for the adjoining ends of two cars of a rapid-transit vehicle includes an apron which is maintained centered in the space between turntables at the adjoining ends, by being mounted on two transverse parallel shafts via telescopable units that are pivoted to these shafts and alternate ones of which, as considered in direction lengthwise of the shafts, exert a biasing action on the apron in mutually opposite directions along the centerline of the two cars.

  • Patent number: 4297926
    Abstract: A machine tool for maching of crankpins on crankshafts, or of similarly ts-axially offset portions of other types of workpieces, includes an arrangement for indexing the workpiece to a plurality of different positions to place new crankpins in position for machining without having to unclamp the workpiece or stop its rotation. Indexing accuracy is greatly improved and all indexing-related operations are powered by the prime mover of the machine tool rather than requiring separate drives.

  • Patent number: 4254694
    Abstract: A coffee machine has an assembly provided with a chamber for receiving a permanent filter selected, according to the taste preference of a user, from a set of such filters which each offer different flow resistance to water per unit time. A pod of ground compressed coffee is also removably receivable in the chamber; the characteristics of pod and filter are so selected that during each operation of the machine between 22-26% of the total aromatic substances present in the coffee in the pod, are extracted by hot water flowing through the pod. However, due to the different flow resistance offered by different filters, the quantity of beverage produced during a predetermined operating time will vary. In dependence upon the particular selected filter, the extracted aromatic substances will therefore be more or less diluted in the beverage, to suit a particular taste.

  • Patent number: 4253385
    Abstract: The invention relates to a coffee brewing machine which is particularly suitable for family use and for a small commercial establishment, such as a refreshment room. The machine extracts the coffee beverage from a pod which contains ground coffee and is housed in a chamber defined by an upper block and by a removable lower box, between a jet-forming member fixed to the upper block and a filter housed in the removable lower box. It includes a water container, a heater and a pump which supplies the water to the chamber at the proper temperature and pressure. In the chamber the water penetrates the pod and extracts the coffee beverage therefrom and then the coffee beverage flows out of the machine.

  • Patent number: 4240528
    Abstract: A field sensor control mechanism for doors and the like has two or more insulated electrodes mounted at different levels in the leading edge of a door or the like. A first oscillating circuit is connected with one of these electrodes and a second oscillating circuit, separate from the first one and serving as a comparison circuit for the same, is connected to the other electrode. The two circuits have base oscillating frequencies which are either identical or differ only slightly from one another. The circuits are so coupled to one another that the oscillations of the first circuit vary as a function of capacitance changes taking place in the electrodes.

  • Patent number: 4218119
    Abstract: A pick-up system includes means for recognizing the displacement of objects to be photographed relative to the optical reproduction plane. The shutter of the pick-up system is actuated according to the relative motion of said objects. In a pick-up system comprising a variable diaphragm and a replaceable film of a special sensitivity, e.g. in an automatic camera, the shutter speed, being a function of the relative motion of the objects, determines the aperture of the diaphragm with respect to the sensitivity of the film.

  • Patent number: 4192146
    Abstract: A body of still water is confined in heat exchange with one or more ambient heat sources whose temperature is usually above but may drop near 0.degree. C. Heat is withdrawn from the body according to the heat-pump principle. If the temperature of the heat sources drops near zero the withdrawal of heat from the body results in the formation of ice in the body and the latent heat of fusion liberated during the ice formation is also withdrawn, so that the time periods during which the temperature of the ambient sources is near 0.degree. C. can be bridged. When the temperature of the ambient sources rises again their heat is used to re-melt the ice in the body of water.
